# Surfpool - Solana Development Environment

The definitive guide for Surfpool - where developers start their Solana journey. A drop-in replacement for `solana-test-validator` that enables local program simulation using Mainnet accounts fetched just-in-time.

## What is Surfpool?

Surfpool is a comprehensive development environment that combines local-first testing with real Mainnet data access:

- **Mainnet Forking** - Clone accounts, programs, and token balances from Mainnet instantly
- **Cheatcodes** - Special RPC methods for time travel, balance manipulation, and state control
- **Infrastructure as Code** - Reproducible, auditable deployments using txtx DSL
- **Surfpool Studio** - Embedded dashboard with transaction inspection and profiling
- **Universal Faucet** - Get SOL, USDC, USDT, BONK from a single interface

### Key Benefits

|---------|-------------|
| **Instant Boot** | No 2TB snapshots, runs on Raspberry Pi |
| **Lazy Forking** | Copy-on-read strategy pulls mainnet data as needed |
| **Full Compatibility** | Works with solana-cli, Anchor, wallets, explorers |
| **Zero Config** | Auto-detects Anchor projects and deploys programs |

# Start with specific runbook
surfpool start -r deployment -r setup
```

## Surfpool.toml Configuration

Create a `Surfpool.toml` in your project root:

```toml
[network]
slot_time = 400
epoch_duration = 432000
rpc_url = "https://api.mainnet-beta.solana.com"

[behavior]
# Fork from mainnet genesis
genesis = false
# Fork from specific point
point_fork = true

[accounts]
# Pre-clone specific accounts
clone = [
  "TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA",  # Token Program
  "ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL", # ATA Program
]

[programs]
# Auto-deploy local programs
deploy = ["./target/deploy/my_program.so"]

[airdrop]
# Default airdrop recipients
addresses = ["YOUR_PUBKEY"]
amount = 10000000000000  # 10,000 SOL
```

## Cheatcodes

Surfpool provides special RPC methods for advanced state manipulation during testing.

### Account Manipulation

#### surfnet_setAccount

Set arbitrary account data:

```typescript
await connection.send("surfnet_setAccount", [
  {
    pubkey: "AccountPubkey...",
    lamports: 1000000000,
    data: "base64EncodedData",
    owner: "OwnerPubkey...",
    executable: false,
  },
]);
```

#### surfnet_setTokenAccount

Create or modify token accounts:

```typescript
await connection.send("surfnet_setTokenAccount", [
  {
    owner: "OwnerPubkey...",
    mint: "MintPubkey...",
    tokenProgram: "TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA",
    update: {
      amount: "1000000000",
      delegate: null,
      state: "initialized",
    },
  },
]);
```

#### surfnet_cloneProgramAccount

Clone a program from mainnet:

```typescript
await connection.send("surfnet_cloneProgramAccount", [
  {
    source: "SourceProgramPubkey...",
    destination: "DestinationPubkey...",
  },
]);
```

#### surfnet_resetAccount

Reset account to mainnet state:

```typescript
await connection.send("surfnet_resetAccount", [
  {
    pubkey: "AccountPubkey...",
    includeOwnedAccounts: true,
  },
]);
```

### Time Control

#### surfnet_timeTravel

Advance network time:

```typescript
await connection.send("surfnet_timeTravel", [
  {
    epoch: 100,
    slot: 50000,
    timestamp: 1700000000,
  },
]);
```

#### surfnet_pauseClock / surfnet_resumeClock

Control block production:

```typescript
// Pause
await connection.send("surfnet_pauseClock", []);

// Resume
await connection.send("surfnet_resumeClock", []);
```

#### surfnet_advanceClock

Advance clock incrementally:

```typescript
await connection.send("surfnet_advanceClock", [
  { slots: 100 },
]);
```

### Transaction Profiling

#### surfnet_profileTransaction

Profile transaction execution:

```typescript
const result = await connection.send("surfnet_profileTransaction", [
  {
    transaction: "base64EncodedTx",
    tag: "my-test-tag",
  },
]);

console.log("Compute units:", result.computeUnits);
console.log("Account changes:", result.accountChanges);
```

#### surfnet_getProfileResults

Get profiling results by tag:

```typescript
const results = await connection.send("surfnet_getProfileResults", [
  { tag: "my-test-tag" },
]);
```

### Network Control

#### surfnet_resetNetwork

Reset entire network to initial state:

```typescript
await connection.send("surfnet_resetNetwork", []);
```

#### surfnet_getClock

Get current network time:

```typescript
const clock = await connection.send("surfnet_getClock", []);
console.log("Slot:", clock.slot);
console.log("Epoch:", clock.epoch);
console.log("Timestamp:", clock.timestamp);
```

## Surfpool Studio

Access the web dashboard at `http://127.0.0.1:18488` for:

- **Transaction Inspector** - View transaction details with byte-level diffs
- **Account Browser** - Explore account state and history
- **Compute Profiler** - Analyze compute unit usage per instruction
- **Universal Faucet** - Request SOL and tokens
- **Network Status** - Monitor slots, epochs, and block production

## Infrastructure as Code

Surfpool integrates txtx DSL for reproducible deployments.

### Runbook Structure

```hcl
# deployment.tx

// Define signers
signer "deployer" "svm::secret_key" {
  secret_key = env.DEPLOYER_KEY
}

// Deploy program
action "deploy_program" "svm::deploy_program" {
  program_path = "./target/deploy/my_program.so"
  signer = signer.deployer
}

// Initialize program
action "initialize" "svm::send_transaction" {
  transaction {
    instruction {
      program_id = action.deploy_program.program_id
      data = encode_instruction("initialize", {})
    }
  }
  signers = [signer.deployer]
}
```

### Running Runbooks

```bash
# Run specific runbook
surfpool start -r deployment

# Run in unsupervised mode
surfpool start -r deployment --unsupervised
```
